Buy a 5 gallon sturdy bucket and take the lid and glue batting and appropriate fabric on the top. It will then be used as an extra place to sit and the inside is used to store supplies. I have seen these at stores and they look really neat and I think they can be made quite easily.

Buy two fleece blankets with strings hanging off the edges. You can find packages of them at AC Moore. Find a pack of hunting/fishing ones. You simply tie the ends together and it creates a warm, cozy hunting/fishing blanket!
